UPDATE: Explosion on Vance Lane leaves one dead, one injured

An explosion in Wilson County left one person dead and another injured Monday night.

Wilson County Emergency Management Agency Director Joey Cooper said WEMA and county officials responded to an explosion at 576 Vance Lane in Lebanon at around 5 p.m.

One person, whose identity was not released, was found dead upon arrival, according to Cooper.

He said the explosion came from inside the two-story, single-family home. He said, contrary to some media reports, the explosion did not originate in a mailbox.

Cooper said the second victim received burns to the face and chest and was taken by LifeFlight helicopter to Vanderbilt University Medical Center.

Cooper said responders put out a small fire at the home.

According to Cooper, agents from the Tennessee Bureau of Investigation are leading the investigation, with the ATF, the state bomb and arson division, the Wilson County Sheriff’s Department and Homeland Security assisting.

Wilson County Sheriff Robert Bryan said all of the agencies are working to determine the explosion's cause and a possible motive. He said officers would remain on the scene through Monday night.

"They will stay out there all night," Bryan said. "The majority of the investigation will pick up in the morning."

Bryan said he wanted to reassure neighbors, including students at nearby McClain Christian Academy, concerning any fears they might have.

"This incident was isolated to this piece of property and confined to that residence," Bryan said.

Authorities could not release additional details by press time Monday night, but Bryan said more information would likely be released Tuesday.
